7−3. How to use filter
The instrument prepares digital filter that can stabilize transferred data into digital through
processor.
Warning ● When setting filter is not adequate, correct measurement can’t be
made and it may cause unexpected accident, so care should be taken
fully.
7−3−1. Digital filter
The digital filter in the instrument can be set from “00000” to “00077”.
Averaged−out times of digital filter can be decided from the set value (Related function F−04).
As for default, “00033” has set. The relations between setting and average−out times are as
follows:
(Averaged−out times)＝2
m＋1
×2
n＋1
m ：Value of 10
1
digit of set value
n ：Value of 10
0
digit of set value
For example, when the setting is “00033”, averaged−out times are as follows :
(Averaged−out times)＝2
3＋1
×2
3＋1
＝16×16
＝256 times
Characteristics tendency due to averaged−out time is listed as below:
Averaged−out times
few
many
Resist to noise rapid stable
Response speed quick slow
